System Overview
Remember When …
Remember when anyone could add a house light channel or a
submaster to a lighting control system by wiring a slide pot to
a diode and attaching it to which ever dimmers they wanted to
control? Remember when control stations could be set up as
independents, or group them with masters all without having to have
a lap top, memorize DMX-512, know Windows 95 or battle the great
configuration labyrinths envisioned by dyslexic software engineers?
Everything was modular and simple. There was not a central
“brain” that required programming, and there was not the hidden
central processor costs and LAN limitations of most conventional
architectural control systems.
Welcome Back to Simplicity
This control system uses 3 small printed circuit board and 2 standard
control protocols – DMX-512 and 0-10VDC as tools to create complex
configurations in the simplest and least expensive way.
The three PCB’s are:
• An on/off Take Control card.
• A break-away, configurable, 0-10 VDC fader board.
• A 6 Channel 0-10VDC to DMX512 Scene Processor.
What experience is Prerequisite?
The only principles a designer needs to understand is:
• Take Control
• Master
• Slave
• Independent
• Snapshot DMX stream
• Pile-On (highest takes precedence)
Previous experience with 0-10VDC, diode patching and/or DMX-512
control protocols and control wiring is helpful, but not essential.

What is needed?
• 0-10 VDC or DMX-512 Dimmers/Ballast’s.
• A DMX-512 Control Console for developing Scenes
(DMX stations only).
• A +12to +16 VDC Power Supply or Analog Stations (this power
supply is not required when used in conjunction with a DMX
Station. See page 3 for current requirements).
• 10V/5VA bell transformer for DMX Stations (the DMX station
will provide 150mA of +V to drive several Analog Stations).
• Standard NEMA Gang Boxes.
• Imagination.
What is not needed?
• A PC, DOS, Windows. Configuration files, disks or download
cables. Station thumbwheel settings, a central processing
cabinet. Lots of patience.

WEB VERSION

DMX Snapshot Record Mode
(For DMX control stations only)
Page 8 of 48
Action Result
• Insure JP1 Jumper is out on
ANA2DMX Processor.
The removed jumper on JP1 puts
the Processor in DMX Snapshot
mode.
• Insure Record Lock is off. Record Lock disables any
attempt to record scenes. D19
LED on ANA2DMX Processor
will be Orange if able to record,
Green if unable to record.
NORecord Lock can be activated any of 3 ways:
1. Jumper JP1 shorted on 2 Channel Analog PCB on station.
2. Jumper JP2 shorted on ANA2DMX processor on station.
3. REC LOCK terminal on ANA2DMX processor on station
driven with external +10VDC signal.
• Turn off all control stations. This insures only console levels
will be recored.
• Bring up the desired scene or
look on the main controls.
This is the scene that will
berecorded.
• Go to the DMX control station.
Slide Master Fader all the way
up to full. Slide all the channel
faders down to out.
This gets the station ready to
beput in record mode.
• Push and hold the ON/OFF
button when turning the station
"ON".
The Green LED will light.
• Count to 5 (approximately 5
seconds - continue to hold the
ON/OFF button).
This puts the Station into record
mode (LED on ANA2DMX PCB
turns green).
WEB VERSION

Action
• Slide master fader to full, channel faders to out.
• Push & hold ON/OFF button when it goes from OFF to ON.
• Count out loud while continuing to hold ON/OFF button:

Page 9 of 48
Action Result
• Slide the Channel Fader up to
full where the scene is to be
recorded (continue to hold the
ON/OFF button).
This snapshots the DMX512 data
stream, saving the entire scene
under the proportional control
of the channel fader that slid to
full. The LED on the ANA2DMX
Processor will blink red when it is
finished recording the scene.
• Release the ON/OFF button. This exits Record Mode.
WEB VERSION

DMX Channel Mode
(For DMX control stations only)
Page 10 of 48
Action Result
• Install Jumper JP1 on
ANA2DMX PCB.
This puts processor in channel
mode.
• Dial up the starting address on
rotary switches SW1, SW2, and
SW3.
This selects the DMX start
address for fader A1.
• For fader channel single pattern
operation, remove JP4.
Faders 1-6 will respond to DMX
channels 1-6 (assuming start
address = 001).
• For fader channel dual wrap
around pattern operation, install
JP4.
Fader 1 controls DMX channels 1
and 7;
Fader 2 controls DMX channels 2
and 8;
Fader 3 controls DMX channels 3
and 9;
Fader 4 controls DMX channels 4
and 10;
Fader 5 controls DMX channels 5
and 11;
Fader 6 controls DMX channels 6
and 12
(assuming start address = 001
and 6 channel operation -
see JP6).
• For highest takes precedence
fader operation, remove JP5.
The fader channels will pile onto
the appropriate incoming DMX
channel levels.
• To replace the incoming DMX
channel levels with the fader
levels, install JP5.
The fader channels will replace
the appropriate incoming DMX
channel levels.
• For 4 channel operation install
JP6 on ANA2DMX Processor.
This puts the processor in 4
channel wrap around mode.
• For 6 or 12 channel operation
remove JP6 on ANA2DMX
Processor.
This puts the processor in 6
channel wrap around mode.

Component Functions
Take control PCB
The take control PCB has a single switch for ON/OFF operation. The
take control PCB requires +12 to +16 Volts DC @ 25mA connected
across +V and common to operate. The PCB provides a regulated
+10.6 VDC source when the ON/OFF switch is activated (turned on)
and 0 Volts when off.
Pressing the ON/OFF switch sends a +10VDC pulse out the
T/C terminal on TB1 and down the T/C wire to reset any other
stations connected to the T/C wire and TB1. The Take Control line
determines and connects the stations you want to respond in a
group. Not connecting the take control line makes the stations or
groups respond independently of each other.
When the ON LED is lit, +10VDC is available on the VOUT terminal.
The VOUT signal can be used to activate a single analog channel,
or when used with prep cable PRP-31316-02, it can be used to
activate several channels at once. The VOUT signal’s most common
application is to implement Panic or Entry Stations. See the Wiring
Diagrams for Entry or Panic stations for more details.
2 Channel Analog Fader PCB
The Fader PCB is a breakable PCB array that can be easily
configured for 1-12 channels with or without a master fader. The
input/output bussed connector scheme of J1/P1 passes DC power,
analog 0-10V levels, and take control across the control station to
the terminal block on the take control card, or to a header for the
ANA-2-DMX PCB. All 0-10V analog channels are buffered by an op-
amp and diode blocked before leaving the PCB.
ANA-2-DMX Scene Processor PCB
The ANA-2-DMX PCB utilizes six 0-10 VDC analog control inputs
to proportionally drive 6 DMX submaster scenes that pile-onto each
other and to the incoming DMX signal whether active or inactive. To
record a scene, first bring up the desired look on the console running
to the DMX IN terminal. Next, slide the master to full and the channels
to off. Push and hold the ON/OFF button to ON for about 5 seconds
on the station, putting the station in record mode.
Page 11 of 48
WEB VERSION

Finally, slide the fader up to full for the channel you wish to record the
scene into. As long as the record lockout is not enabled, the scene
will be saved onto that channel, and will proportionally fade relative to
the slide pot. For user convenience, the record lockout function which
disables re-recording scenes is available on the DMX terminal Block,
as a jumper on the ANA-2-DMX PCB itself, and also as a jumper
on the 2 channel fader PCB. Record lock is perfect for setting up
house light channels or looks, and then disabling the record function
for patrons. A DMX bypass relay is provided in the event of a power
supply failure.

System Design Considerations
Place HHR or DMX-512 IN jacks near DMX
stations
Place a Hand Held Remote Jack from the control console or a DMX-
512 IN Jack where the console could be plugged in near any station
that will be used to snapshot scenes on a frequent basis. This way
scenes can be activated from the console in the same place they are
to be recorded.
Power Supply Requirements
DMX Station Current Supply
(+V/COM power supply source for a single station connected to a
single 10V/5VA transformer)
NOTE: The +V/COM current through a DMX station should
not exceed 750mA.

Current Calculation Examples
3 Grouped Stations
Current demand calculation for qty 3, 6 channel stations connected in
a group; T/C connected between stations, therefore only one station
can be on at a time.
+V Amps = 50mA (station 1) + 5mA (station 2)
+ 5mA (Station 3) = 60mA
3 Independent Stations
Current demand calculation for qty 3, 6 channel stations connected
independently; T/C not used. All 3 could be on at the same time.
+V Amps = 50mA (station 1) + 50mA (station 2)
+ 50mA (Station 3) = 150mA

Eliminate Ground Loops
What is ground?
This control system, like most other control systems requires a
common reference for the electronics to function properly. This
reference is typically denoted as Common or Ground. Control
voltages are measured with respect to this ground reference,
just like the height of a person would normally be measured with
respect to the ground they are standing on. Without a proper
common reference, the electronics can not make accurate voltage
measurements, and therefore will not function correctly.
Keep COM and GND separate
The ANA2DMX PCB has 2 different control references - COM (Analog
Common) and GND (Digital Ground). The two are nearly the same,
except COM is the reference for all the analog control levels and GND
(digital ground) is the reference for the digital electronics and the
incoming power supply. COM and GND should never be connected
together with external wiring. Never place This control systems
control lines in conduit with other wires, or flickering problems could
occur.
Make star or daisy chain connections
In this electronics system, it is important for all the COM signals to
be connected in a start or daisy-chain configuration, as opposed
to a ring or loop configuration. The reason is that a ring or loop
configuration usually acts like a big antenna which is excited and
aggravated by adjacent power lines. Apply the following rules:
DMX daisy-chain configuration rules
(Multiple DMX Stations connected in serial along one DMX-512
line)
1. Do not connect COM between DMX stations.
2. Use a separate power supply for each DMX station.
3. Daisy-chain the DMX-512 signal as normal, connecting the
shield drain to DGND.
Page 17 of 48
WEB VERSION

DMX bridge rules
(2 or more DMX Stations tied together with COM, each
processing its’ own DMX-512 line)
1. Tie stations together using COM.
2. Use a separate 10V/5VA transformer for each DMX Station.
3. Connect the shield drain wire to DGND on the DMX-1 station.
4. Do not connect the shield drain wire to DGND on additional
DMX stations (DMX-2, 3, 4 ...). Leave the DGND Terminals or
DMX IN/OUT empty. The DMX shield can be passed through
the station location, but it should not touch or connect to
anything in the box.

Advanced Topics
Use of blocking (steering) Diodes
What is a Diode?
A diode is a one-way valve. It allows current to flow in a forward
direction, but not in a reverse direction. The input is the anode, or un-
banded end of the part; and the output is the cathode, or banded end
of the part. When the input (anode) is at a voltage potential higher
than the output (cathode), current will pass from the input to the
output until it fills up the output connection to nearly the same voltage
level as available on the input connection. When the output voltage
rises higher than the input voltage, the part shuts off.
Analog Channel Grouping
Use 1N4148 or 1N914 diodes to select multiple Analog Channels to
be controlled by a single fader, Entry, or Panic station. This is done
by connecting the banded end (cathode) of the diodes to each of the
Analog Channels to be controlled. Tie the un-banded ends together,
and to the single VOUT or A (1-6) single fader control line that is
to control the channels. The diodes will keep the channels to be
controlled separate except when the source channel is active. The
1N4148 or 1N914 is considered a signal diode. It is excellent for quick
linear response in low-current applications, however it has a tendency
to fail in high current applications.
Master/Slave Take Control
Use 1N4004 diodes to create Master/Slave take Control relationships
between control stations. This is implemented by attaching the un-
banded end (anode) to the master station, and the banded end
(cathode) to the slave station(s). The master station will now be able to
take control away from the slave station(s), but the slave station(s) will
not be able to take control away from the master station. The master
station will act as an independent from the slave(s) stations point of
view. The slave station will also be unable to record presets if the
master station is a DMX station, as the record operation is a function
of the take control circuit.
Page 19 of 48
WEB VERSION

The 1N4004 is considered a rectifier diode, and is excellent for
high-current applications, like the take control circuitry, but it would
perform poorly as a signal diode, because it requires significant
current to operate properly.
